The Otter Blocks WordPress plugin before 3.2.8 does not correctly bound a pattern it uses to rewrite its dynamic-content tokens while rendering blocks, so the pattern can consume the quote that closes an HTML attribute and pull adjacent unescaped data into the markup as new attributes. This allows unauthenticated users to achieve stored Cross-Site Scripting that executes in the browser of any visitor who views an affected page, including a logged-in administrator.

The Otter Blocks WordPress plugin before 3.2.8 does not enforce its block visibility conditions when a published post is rendered through the WordPress REST API, allowing unauthenticated users to read block content that the site owner restricted to specific roles, logged-in users, the post author, categories or tags, or (on the Pro tier) Stripe purchasers.

The Otter Blocks WordPress plugin before 3.2.8 does not properly sanitize and escape user-supplied block styling values before writing them into an inline stylesheet, allowing users with contributor-level access and above to inject arbitrary web scripts that execute when any visitor, including administrators, views the affected post.

The Otter Blocks WordPress plugin before 3.2.8 does not correctly determine whether a post is publicly readable before returning its data through a REST API endpoint, treating any post with the published status as public, allowing unauthenticated users to read manual excerpts of password-protected posts, the content and titles of non-public post types, and, on WooCommerce sites, coupon codes and their descriptions.

The Otter Blocks WordPress plugin before 3.2.3 does not validate that a user-supplied return URL belongs to the site before using it to build the return destination of a Stripe Checkout session, allowing unauthenticated attackers to redirect victims who complete or cancel checkout to an arbitrary external URL.

The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'media:thumbnail@url' parameter in all versions up to, and including, 5.2.11 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the attacker to control an external RSS feed that the target site has already configured for import; no WordPress account or special plugin configuration is needed beyond that condition.

The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Feedzy Loop Block Feed URL / RSS <title> in all versions up to, and including, 5.2.10 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is not neutralized at save time because postcontent stores only a benign block reference to an external feed URL; the malicious HTML is injected at render time from the attacker-controlled RSS feed title, bypassing any save-time wpkses filtering.

The MPG WordPress plugin before 4.2.3 does not properly validate the structure of imported project data before using it in a database query, allowing users with the Editor role or higher to perform SQL injection attacks and read sensitive data such as password hashes.

The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.6 via the 'otterformwidgetfilter' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the email addresses of the five most recent form submitters, their submission dates, and the site's total form submission count. The widget is registered whenever the themeisleblocksformemails option is non-empty — the normal state after any Form block has been saved — meaning the exposure is active on any standard site using the plugin's form feature.

The Kirki WordPress plugin before 6.2.3 does not properly validate the files contained in archives uploaded by users with the Editor role, and does not remove all unwanted files after extracting them, allowing such users to upload arbitrary files to a web accessible directory, leading to Stored XSS as well as RCE on some server configurations.

The Orbit Fox: Duplicate Page, Menu Icons, SVG Support, Cookie Notice, Custom Fonts & More WordPress plugin before 3.0.8 does not sanitize uploaded SVG files when its SVG upload feature is enabled, allowing authenticated users with the upload capability (Author and above by default, without the unfilteredhtml capability) to upload SVG files containing JavaScript that executes in the site context when the file is viewed, leading to Stored Cross-Site Scripting.

This only affects multi-site installations and installations where unfilteredhtml has been disabled.

The Multiple Page Generator Plugin – MPG plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.0.5 via the 'mpgdownloadfilebylink' function.
